Abstract

Indonesia’s location in a high seismic hazard zone underscores the need for earthquake-resistant structural systems. This study evaluates the seismic performance of a six-story apartment building by comparing reinforced concrete and steel structural systems. Nonlinear static pushover analysis was conducted in accordance with ATC-40 procedures using SAP2000 software. The case study focused on the ASN PUPR Apartment in Aceh Besar. In the X direction, the reinforced concrete structure developed a maximum base shear of 16.196.842 kN with a lateral displacement of 0.158 m, while the steel structure sustained 15.594.735 kN with 0.229 m displacement. In the Y direction, the concrete structure reached 13.880.619 kN with 0.173 m displacement, while the steel structure developed 9.083.022 kN with 0.216 m displacement. Performance point analysis indicated that the steel structure exhibited greater deformation capacity and energy dissipation, as reflected by higher spectral displacement (Sd) and spectral acceleration (Sa) values. The concrete system displayed higher initial stiffness but lower ductility, while the steel system provided more flexibility with extended plastic deformation capacity. Both systems achieved the Immediate Occupancy (IO) performance level, indicating post-earthquake functionality. The results emphasize the importance of selecting structural systems based on design priorities: reinforced concrete for initial stiffness and vertical stability, and steel for improved ductility and energy dissipation under seismic loads.
